Needle bed insert blank forming die for computer knitting flat knitting machine

Abstract

The invention discloses a needle bed insert blank forming die for a computer knitting flat knitting machine and belongs to the field of dies. An upper die mechanism comprises an upper die plate frame, an upper die plate and insert male stamping dies, and a lower die mechanism comprises a lower die plate frame and a lower die plate. The needle bed die insert blank forming die is characterized in that one side, which faces the lower die, of each insert male stamping die has a relatively higher end and a relatively lower end; the height difference between the relatively higher end and the relatively lower end is equal to the thickness of a needle bed insert blank to be subjected to stamp forming; the upper die mechanism comprises a pressing plate; the pressing plate is connected with one side of the upper die plate; guiding die holes are formed in the pressing plate, two sides of the pressing plate are provided with a group of first guiding screw holes respectively; second guiding screw holes are formed in two sides of the upper die plate; thin steel strip guiding and limiting mechanisms are arranged on one side of the lower die plate; each thin steel strip guiding and limiting mechanism comprises a guide rod and a spring; and charging grooves are formed on the lower part of the lower die plate frame. The needle bed insert blank forming die has the advantages that the quality of the blank is guaranteed, and the equipment investment is reduced; the stamping quality is guaranteed; unqualified blanks cannot be generated; and the needle bed insert blank forming die can be applied to needle bed insert blank collection.

Description

technical field [0001] The invention belongs to the technical field of moulds, and in particular relates to a mold structure for forming a needle bed blank body for a computerized flat knitting machine. Background technique [0002] As known to manufacturers of computerized flat knitting machines and manufacturers using computerized flat knitting machines to produce fabrics, the knitting needles of the knitting mechanism of the flat knitting machine extend out of the needle grooves of the needle bed when transferring and receiving needles. The distance is much longer than the distance extending out of the needle bed during normal knitting, so a needle bed insert is required on the needle bed, and the needle bed insert can protect the knitting needles and prevent the knitting needles from performing operations such as transfer and stitching. During the stitching process, tampering and / or deflection occur due to protruding from the needle bed, and finally avoid broken needles ...

AI Technical Summary

Problems solved by technology

In addition, there are still the following technical problems in the structure of the mold for forming the needle bed blank body in the prior art: First, when the step-type feeding mechanism sends the thin steel strip to the lower template, there will be a swimming offset, thereby affecting The stamping effect even produces waste products; secondly, due to the flexibility of the thin steel strip, when it is fed to the lower formwork by the step-by-step feeding mechanism, it will have a tendency to arch, so it acts as an insert on the upper formwork. Convex die facing the lower template will be affected when the thin steel strip is stamped to form the needle bed blank, which increases the probability of defects and even leads to the scrapping of the needle bed blank; third, there is a lack of needle bed blanks for collection and forming The blank body measures make the stamped needle bed insert blanks scattered on the ground, which increases the workload of subsequent cleaning
